Comment:
according to https://ffmpeg.org/trac/ffmpeg/ticket/1776 : PAR = DAR/SAR
[[BR]]
so for first " Stream #0:1(eng): Video: h264 (Constrained Baseline) (avc1
/ 0x31637661), yuv420p, 160x120 [SAR 1:1 DAR 4:3], 224 kb/s, 23.97 fps,
23.97 tbr, 2397 tbn, 47.94 tbc"
** SAR=1:1 , and PAR=(4:3)/(1:1)=4:3 **
for second Stream #0.1(eng): Video: h264, yuv420p, 160x120 [PAR 1:1 DAR
4:3], 224 kb/s, 23.97 fps, 23.97 tbr, 2397 tbn, 47.94 tbc
** PAR=1:1 , and SAR=DAR/PAR=(4:3)/(1:1)=4:3 **
though i use different version ffprobe/ffmpeg, but i get different PAR and
SAR value , ** which value i can trust or which version i can trust ? **
